Advanced GLSL 2D Filters

Posted on by

mount1Martinsh has come up with some amazing screenshots of a mountain landscape in the Blender Game Engine, which utilizes some of the new 2D filters being developed. The landscapes are some of the most impressive and detailed pieces of art I’ve ever seen in the BGE.

Martinsh has been working on integrating a bunch of new GLSL filters, including Chromatic Aberration and SSAO (Screen Space Ambient Occlusion), among others. The SSAO is particularly impressive (see top right image below), which Mike Pan (mpan3) helped to develop. This demo uses SSAO+sunrays+chromatic_aberration+DoF.

Theres a thread on Blenderartists.org with full sized pictures detailing each individual component of the realtime rendering, the thread is also good for keeping track of updates and leaving comments/questions.

On a final exciting note – Martinsh has just released the .blends earlier today: Download link – Link(1)

The ‘game’ controls:

“WASD – move camera
Left/Right arrows – move sun
Filters:
1 – SSAO only
2 – SSAO + scene
3 – Light scattering
4 – DoF (mousewheel – change focus)
5 – Chromatic abberration
6 – Cross shaped bloom”

Of course make sure to realize all of this is very new and requires a very powerful computer to run properly. Martinsh is hoping to optimize the filters more soon, which will be made a lot easier when downsampling gets integrated.

      Very nice. I’m seeing some great stuff being done in the GE! Its so good to see it come back to life!

      wow, looks nice and runs at 30 fps with everything on. the filter controls are just a bit odd :p
      Would love to see a tutorial on how to do this

      Wow, that’s impressive :O, looks fine.. a little bit slow, but nice :)

      My antivirus said that there is trojan inside Link(2), filedropper.

    • SAJ

      Yes me too! Be carefull with link 2….

      Ok guys, thanks for the virus alert, I’ve removed the second link completely as a precaution. The first one works fine either way. Ill let Martinsh know on his forum thread.

      I’m not a GE fun, but this looks great! … amazing it’s real-time.

      I’m assuming the download link is flooded… I can’t get it to download at all.

      All the effects from Crysis in the GE, great work! :)

    • T-Rev

      Doesn’t work for me. Well, some of it does. I have 2 ATI HD Radeon 3870 cars in crossfire.

      Do we need a svn version of Blender?
      Or the stable release is enough?

      This works on Windows on a Mac but not on OS X on the same machine. Both 2.48. The Mac one doesn’t enable any effects, I don’t know if it’s a keyboard numbering thing or to so with the shaders. All effects work as expected on the Windows OS.

      Runs a bit slow for me – 10fps or so – but it looks great.

      Usually I see something posted and it fills me with nostalgia for things I’ve done, or not done right. This time, it’s awe and wonder.

    • jacques

      this is amazing!

      This is really nice. If anybody here’s ever played Shadow Of The Colossus, you’ll know how powerful these sorts of filters can be!! The lighting in that game is amazing, thanks to it’s awesome filters. Nice to see Blender getting this sort of stuff in the BGE! =]

    • nate

      Me and a team are working on a game called Present fear. I was wundering if I could have a tutorial.
      We might put it in the game.Also is there a way to lower the quality for lower end users?

      this is crazy man !!

    • yokljo

      AMAZING!!! Looks like a render… maybe even better :P I used to think the GE idea would get dropped, but it just keeps getting more and more awesome! Keep it up

      OMG!

    • Stamem Worlslmore

      I would like to use screen-space ambient occlusion during high-poly sculpting, is this possible?

    • Thomas

      This is just plain awesome. I have some problems with it though.
      1. I have to move the little plane on the camera to see anything, although I don’t have to for an actual render.
      2. All I get is very white/greyish color, and close to 50 fps.
      3. When I press 4, Blender crashes.
      5. In a render, the moon’s plane stands out instead of blending in with everything.
      6. I can’t resize or split views.
      Renders do look great, and take a surprisingly short amount of time.
      I don’t know if my problems are just from lack of good hardware, or from the OS, but my hardware is:
      AMD Athlon XP 1.4GHz 1GB DDR RAM
      ATI Alli-in-Wonder Video 128mb
      Running Windows 2000
      (I would have something better, but this is my brother”s computer.)
      My guess is that either my card doesn’t support something, or Win2000 is causing problems.
      I’m using 2.48.
      No SVN or anything.

      Really impressive, love it!

      amazing, great work. I wish i could do that python scripting..

    • martinsh

      Thanks, guys!

      Im really sorry if the second link caused any problems, it somehow got infected in Filedropper.com servers after uploading it. Now looks like all filedropper.com files are deleted.

      here is another link to blend file hosted in trusted server ;)

      @nate
      there are a lot of values that can be tweaked inside the codes for better performance/lower visual quality. For light Scattering, try lowering the NUM_SAMPLES value. Anyways, unless the downsampling gets integrated in BGE, the 2D Filters like bloom or blur will always be slow.

      @Stamen
      no not at the moment, but someone who is more experienced in coding, could hardcode it in Blender and make a SVN build.

      @Thomas
      This demo requires powerful system to run properly, also there is incompatibility with ATI graphics cards at the moment, im not sure why.

    • martinsh

      ahh, i forgot to mention, that this work (2D Filters) is part of a big Blender game Twilight22, though not yet announced.

    • nate

      Are the filters entirely coded in phython? Im just wundering because im learn phython.
      Thanks for working on this,

    • martinsh

      nate, no it is GLSL (OpenGL Shading Language), based on C programming language.

    • Thomas

      OK, Makes sense. Still great work though!

    • Odell

      Please stop using services that limit download speeds and ask to pay money. That’s seriously annoying. Try something like Mediafire or even a mirror site with unlimited bandwidth.

    • Michael

      Thank you so much for providing this to the blender community.
